Motion Control Levers and Parking
Brake Position
The motion control levers located on each side of

The motion control levers are speed sensitive controls
of independent wheel motors. Moving a lever
forward or backward turns the wheel on the same side
forward or in reverse; wheel speed is proportional to
the amount the lever is moved.
Moving the control levers outward from the center
T-slot position engages the parking brake on the drive
wheels. Always position the motion control levers
into the parking brake position when you stop the
machine or leave it unattended. The machine must be
tied down and brake engaged when transporting.
